IPC: E05D15/52
Filed: 1974-06-18
Abstract: The window with a rotating and tilting ac actuating mechanism has a manual actuating lever for ensuring alternative locking, rotating and tilting positions of a moving window frame. The special feature is such that windows can also be operated by children without the danger of falling out. The window rotating panel can be locked in its closed position. The rotating arrangement of the window rotating panel has a locking element is contructed so that it cannot be released from the unauthorised side. A special key is required for this purpose which release the locking arrangement when the window is tilted. The locking arrangement (17) for the window moving panel in the closed position is dependent from the actuating hand lever (13). This locking arrangement can be released especially when the window moving panel is tilted.

Title: Tyre with smaller emergency inner tube resting against beadings - via projecting ribs to prevent friction damage
Inventor: HENNING HERMANN
IPC: B60C15/032
Filed: 1974-08-12
Abstract: A pneumatic (tubless) tyre has a safety inner tube bearing agains the tyre beadings but not in contact with the tread region of the tyre under bormal circumstances. Contact between this inner safety tube and the beading regions and/or the rim of the wheel is via a number of elastic projections, either along the inner shoulds of the tube, or along the corresponding opposite faces of the beading region and/or on a ring resting in the trough of the wheel rim. These projections pref. constitute deformable, flat rectangular st strips or ribs running in the circumferential direction of the tube. If, when the outer tyre becomes depressurised, contact occurs between it and the inner tube, then the resultant progressive slip of the inner tube around the wheel caused by the differences in circumfererence of the two tyres does not result to damage at the contact regions on account of the ability of the projecting shoulders to deform. Thus the phenomenon of progressive deformation and sudden 'jump' of the tube is virtually eliminated and damage does not occur.

Title: Heat engine cooling liquid alarm circuit - submerged electrode is earthed when liquid is at a required level
Inventor: CID SORIANO JOSE DEL
IPC: F01P11/16
Filed: 1974-08-12
Abstract: The electric device for temperature and leakage control of a heat engine cooling liquid has an earthed electrode which is submerged to predetermined height in the cooling liquid and which is connected to the control valve of an electronic circuit breaker unit. The latter has at least one input from the source and at least one output operating a signaling device. The electrode/valve is in the off position while the level of liquid is maintained and electrode is then earthed. The lowering of the liquid level prevents the contact with earth, the change of the state of the switch and the emission of alarm signals.

Title: Continuous exhaust gas volume measurement method - inlet air of IC engine measured by pressure drop method
Inventor: PAZSITKA LASZLO DIPL PHYS DR
IPC: G01F1/36
Filed: 1974-09-14
Abstract: Inlet air volume of an i.c. engine is continuously measured by the pressure drop method, as a proportional measure for the exhaust gas volume in accordance with the combustion equation.

The blower or supercharger (7) draws the motor exhaust gas and the diluting air from lead (8) with filter (9). The combustion air can be measured by effective pressure generator (10), or the diluting air can be given via pressure generator (13). The exhaust volume can also be calculated from the pressure value behind the blower (7).

Title: Control and current recovery circuit - for high speed printing electromagnets operated by pulses through semiconductor switches
Inventor: HAVERKAMP KARL-HEINZ
IPC: H01F7/18
Filed: 1974-11-02
Abstract: The magnets have a high self-inductance voltage and are shunted by capacitors for storage of the voltage generated by the magnets disconnection. An additional charging circuit is in series with the capacitor and responds, after each control cycle, and recharges the capacitor to a present value. A capacitor (C) common to all magnets is recharged by only one additional charging circuit. Each magnet is connected to it through a diode of a polarity opposite to the capacitor charge. In order to connect or disconnect an individual electromagnet to or from the capacitor voltage (Uc), each diode is shunted by the emitter-collector path of a transistor.

Title: Floating tar processing - by skimming off retarder level and treating in disintegrator before recycling
Inventor: GRULICH HEINZ
IPC: C10B45/00
Filed: 1974-11-16
Abstract: Floating tar, which forms a forth of tar, solids, water and gas bubbles on top of the crude tar in the collecting main of coke ovens and in the detarrer, is skimmed off by a paddle wheel and collected in a torugh. It slides by gravty into a disintegrator where it is homogenised, ready for recycling into the normal tar processing circuit. This saves the expenditure for separating the floating tar and burning it. The disintegrated floating tar causes no difficulties in the subsequent treatment stages which it passes together with the crude tar.

Title: Pulse frequency meter with microphone in pressurisable cuff - includes comparator for converting Korotkoff sounds to rectangular pulses
Inventor: SCHWAB MARTIN
IPC: A61B7/04
Filed: 1976-04-27
Abstract: Pulse frequency meter comprises a pressurisable cuff in which is inserted a microphone which picks up Korotkoff sounds occurring on pressure reduction, to provide a pulse frequency indication from the time sequence of these sounds. A comparator converts the amplified sounds to rectangular pulses each of which is converted by a monostable trigger circuit to a measuring pulse of constant amplitude and duration. For a given time, these measuring pulses are transmitted to an integrator which adds them up to form a measuring voltage. The amplitude and duration of the pulses, and the measuring time, are such that the measuring voltage is proportional to the number of pulses per min., and this voltage controls an indicator.
